Acuity Technologies Inc. introduced its ISS line of intelligent servos at AUVSI 2010. The servos are designed as compact sealed actuators for autonomous and remotely controlled vehicles in aerospace, surface, marine, and industrial robotic applications.

Available in industrial and extreme environment grades, the line of servos is capable of 1 to 12 Nm of torque and speeds from 15 to 500 rpm. They can be controlled via CANBus, serial lines, pulse-width or analog signals, and will accept 12 to 48 Volts power. A single power/signal cable simplifies installation. The wide speed and power range makes them suitable for control surface actuators, retractable landing gear, drive motors for wheeled or tracked vehicles, and robotic arms.

"These servos fill a need for power and reliability above the high-end R/C servos, where virtually no standard products have previously been available." said Robert Clark, Acuity's president. "We started out looking for servos for a Navy UAS but had to build them, due to the lack of selection in speed, power, and form factor." For those requiring high reliability, configurable status/error reporting allows monitoring of servo status and bus integrity. The servos may be operated in position, velocity, or torque mode, with update rates of up to 1000 per second for high performance autopilot or human control.

The Network Servo Controller provides a single serial interface and power distribution for a network of up to 32 servos in a star/daisy chain topology.
